Engaging with Social Media: Implications for COVID-19 Research Participation Among Adults Living in the State of Florida.

The COVID-19 pandemic led to an increased use of social media, with many people turning to it for social support. Given the varying effects of social media, this study examines how social media use influences the willingness of adults in the State of Florida to participate in COVID-19-related research. The study used data collected through the Florida Statewide Registry for Aging Studies (FSRAS), which included 587 participants who were 25 years and older. The primary outcome variables were COVID-19 treatment and COVID-19 vaccine research. Ordinal logistic regression was used to evaluate the association between social media use and willingness to participate in COVID-19 treatment and vaccination research, adjusting for sociodemographic variables. The analysis did not find a statistically significant relationship between social media use and the likelihood of participating in COVID-19 research. However, significant differences were observed across racial/ethnic groups. Participants who identified as "Hispanic/Latino" (OR-2.44, 95% CI-1.11-5.35, p = 0.03) and "Other" (OR-12.51, 95% CI-1.98-79.22, p = 0.01) were significantly associated with willingness to participate in a COVID-19 treatment research. Similarly, participants of all other races/ethnicities were significantly more willing to participate in research testing COVID-19 vaccines. Additionally, females were more likely to express willingness to participate in COVID-19 vaccine research. Social media use did not significantly affect willingness to participate in COVID-19 treatment and vaccine research; however, racial and ethnic differences significantly influenced willingness to participate. These findings suggest that implementing targeted culturally sensitive recruitment strategies and community engagement efforts can improve participation in COVID-19 research.

Keeping Patients Safe Online: A Study of Refractive Surgery Advertisements on Social Media.

Introduction Refractive error is the leading cause of visual impairment and blindness globally. Increasingly, patients are exposed to information about refractive surgery through social media advertisements. While national guidelines specify how refractive surgery should be advertised in traditional media, it is unclear to what extent these standards are adhered to in the emerging commercial arena of social media. The adherence of refractive surgery advertisements on social media to professional standards is poorly studied. Method We retrospectively analyzed the content of refractive surgery advertisements on the social media platform "TikTok," shown in the United Kingdom (UK) from October 2022 to October 2023, and compared them to the guidelines set out by The Royal College of Ophthalmologists (RCOphth) and the Advertising Standards Authority (ASA). Results We found that 39/51 (76%) of advertisements did not state the specific pathology to be corrected, and 41/51 (80%) did not specify a surgical procedure. Additionally, 33/51 (65%) of advertisements included at least one financial inducement, 44/51 (86%) contained misleading claims. None of the analyzed advertisements provided specific prices, offered refractive surgery as a competition prize, or featured celebrity endorsements. No medical jargon was found in any of the advertisements. The most viewed advertisement was seen by over 1.2 million unique users, with the median number of views for all advertisements being 34,000. Conclusion In conclusion, our analysis revealed that none of the refractive surgery advertisements on a popular social media platform met the standards set by RCOphth or ASA. This study presents the first qualitative analysis of social media refractive surgery advertisements, offering insights into what users can expect and providing recommendations for patients, doctors, social media platforms, and regulators to enhance refractive surgery advertising in the future.

Emotional exhaustion weakens the relationship between social media use and knowledge sharing behavior.

PURPOSE: Knowledge sharing behavior is crucial for ensuring organizational success, fueling innovation, solving problems, and informing decision-making. While social media platforms offer powerful tools for employees to share knowledge, the intricate relationship between social media use and knowledge sharing behavior remains unclear. Few studies have examined the influencing mechanisms of emotional exhaustion on the above relationships, especially through self-determination perspective. DESIGN/METHODOLOGY/APPROACH: As knowledge is inherently private to the individual, grounded in self-determination theory, this study employed a moderated mediation analysis to explore the internal mechanisms of social media use on employee knowledge sharing behavior. The survey of 356 full-time employees was collected from a large environmental protection group in China. Hypotheses are tested using hierarchical regression analysis and bootstrap tests. FINDINGS: The results show that social media use positively affects employee knowledge sharing behavior; knowledge sharing intention partially positively mediates the influence of social media use on knowledge sharing behavior; emotional exhaustion negatively moderates the relationship between social media use and knowledge sharing intention. CONTRIBUTION OF RESEARCH: The study identifies how two styles of social media use - work-related purpose and social-related purpose - affect knowledge sharing behavior. It significantly advances the understanding of social media use on knowledge sharing behavior from self-determination perspective. PRACTICAL IMPLICATIONS: This study has several important practical implications for organizations seeking to facilitate employee knowledge sharing behavior through social media use. Organizations should improve employees' knowledge sharing intention and avoid emotional exhaustion.

Problematic social media use and vaping among Mexican-American college students.

Introduction: Social media use and vaping nicotine are highly prevalent in the daily lives of young adults, especially among Mexican-American college students. The excessive and compulsive use of social media platforms, coupled with the urge to stay continuously connected, can lead to problematic social media use. To date, no studies have explored the impact of problematic social media use on the daily patterns of vaping among this vulnerable population. Methods: In Spring 2023, we employed Ecological Momentary Assessment over a period of 14 days to collect real-time daily data on participants' social media use and vaping behaviors via a mobile phone-based application. Participants were 51 Mexican-American college students aged 18-25 years, 72.5% female, who were current vapers. We used generalized linear regression models to examine differences in vaping behaviors among participants with and without problematic social media use. All regression models adjusted for age, sex, and SES. Results: Participants with problematic social media use vaped on an average of 5.9 days compared to 5.7 days reported by those without problematic social media use (p < .05). Problematic social media use is associated with more frequent daily vaping [b = 0.03; 95% CI: 0.02-0.05], increased number of days vaping [b = 0.14; 95% CI: 0.07-0.20], and vaping higher nicotine concentrations [b = 0.08; 95% CI: 0.03-0.14]. Conclusion: Results suggest that problematic social media use significantly increases the risk of daily vaping among Mexican-American college students. Findings highlight the need to strengthen digital resilience and social media literacy to help college students navigate and mitigate the risks of social media.

Solitary Experience and Problematic Social Media Use Among Young Adults: A Systematic Review with Recommendations for Future Research.

Objective: This study was conducted to summarize existing studies on the association between solitary experiences and problematic social media use (PSMU) among young adults. Method: A systematic review was performed according to the PRISMA guidelines, implemented in Scopus, Web of Science, PubMed and PsycINFO. We selected studies if they presented original data, assessed solitary experiences and PSMU in young adults (i.e., 18-30 age range), were published in peer reviewed journals between 2004 and 2023, and were written in English. Results: After duplicate removal, 1,841 eligible studies were found. From these, 12 articles were selected, encompassing 4,009 participants. Most studies showed a positive association between general loneliness and PSMU. Some of these suggested that this relationship varies based on the facets of loneliness, other potential variables, and the type of social media. No mediating factors were found. Few studies assessed solitary experiences other than general loneliness, highlighting the need for a multidimensional perspective on solitary experience in investigating PSMU. Conclusions: Implications and future research orientations are discussed.

Understanding what drives adolescent social media behaviours: Informing approaches for interventions.

While much research has explored the impacts of social media use, less is known about what factors drive use. The present study examined the relationships between potential drivers of social media use; namely social media literacy, motivations, and internalisation of appearance ideals, and determined whether they work in combination or individually to predict a range of social media uses and behaviours over time, including intensity, frequency, exposure to fitness and celebrity content, photo editing, appearance comparisons, and types of use. Australian adolescent girls (n = 704) and boys (n = 938) aged 11-16 years completed online surveys at baseline and 6-month follow-up. Bivariate correlations and multiple regressions were performed separately by gender. Results revealed weak associations between drivers and found they uniquely contributed to social media behaviours, though this was dependent on use outcome. Thin- and muscular-internalisation were related to some appearance-focused use (e.g., comparisons, following celebrity and fitness accounts) among girls and boys, respectively. Critical thinking was associated with lower Snapchat use among boys and motivations were related to intensity and type of use (i.e., viewing, posting). These findings suggest multicomponent holistic interventions targeting numerous drivers may be most appropriate in modifying social media behaviours among adolescents.

Psychological distress, social media use, and academic performance of medical students: the mediating role of coping style.

BACKGROUND: Given that social media use (SMU) is an increasingly widespread activity among university students, more information is needed to evaluate its relationship with students' mental health, particularly medical students. OBJECTIVE: The present study assessed the relationships between SMU and coping style with psychological distress and academic performance of medical students. METHODS: An offline cross-sectional survey conducted with 398 undergraduate medical students. The survey collected data on demographics, psychological distress (DASS-21), coping strategies (Brief COPE Scale), academic performance (grade point average) and estimated average time spent on social media per day. Structural equation modeling was used to clarify relationships between the main study variables. The study also examined the mediating effect of maladaptive coping between SMU and psychological distress. RESULTS: Students with higher levels of psychological distress were more likely to be engaged in frequent social media use. Spending more than two hours a day on social media use had a positive association with maladaptive coping (p < 0.001), particularly with substance use and behavioral disengagement both of which could negatively affect academic performance. Maladaptive coping mediated the relationship between students' SMU and psychological distress. CONCLUSION: The findings suggest that medical students commonly use social media as a maladaptive coping tool to deal with psychological distress. Empowering students to adopt and foster appropriate coping strategies could help them to enhance resilience against life stresses and ameliorate potential long-term mental health consequences associated with maladaptive behaviors.

Social media use, mental health and sleep: A systematic review with meta-analyses.

BACKGROUND: The literature investigating the relationship between social media use, mental health, and sleep has produced inconsistent findings. Younger people spend more time on social media than other age groups, and are more likely to be impacted by social media use. This systematic review with meta-analysis aimed to synthesise the evidence on the associations between social media use, mental health, and sleep of young individuals. METHODS: Electronic databases PubMed, Scopus and PsycINFO were searched using an established methodology and pre-determined search terms for studies that reported the association between social media use, mental health, and sleep. RESULTS: The search yielded 6108 articles, of which 182 (n = 1,169,396) were eligible for the systematic review, and 98 (n = 102,683) could be included in the meta-analyses. The systematic review identified a high level of heterogeneity in the study results. Meta-analyses found small but significant positive associations between social media use, depression, and anxiety. In addition, problematic social media use was positively associated with depression, anxiety, and sleep problems, and negatively associated with wellbeing. Geographical location, anxiety measure type, study design, age, and gender were identified as potential moderators. LIMITATIONS: Associations for specific social media platforms as well as some moderator effects were not examined due to an insufficient number of studies. CONCLUSIONS: This study provides important evidence of an association between social media use/ problematic social media use, mental health, and sleep. The findings support future longitudinal research to identify the directions and underlying mechanisms of the inter-relationship between these variables.

Effects of social media use on employment anxiety among Chinese youth: the roles of upward social comparison, online social support and self-esteem.

Based on the continuous development of new media and mobile communication technologies, social media has significantly influenced people's daily thoughts and behaviors. For young people, social media is a platform for social interaction, and studies have found that social media helps Chinese graduates find employment. This study examined how social media use and its related factors affect employment anxiety. The data was collected from 1,204 Chinese youth through an online survey. The results showed that: (1) the intensity of social media use had a positive predictive effect on employment anxiety; (2) upward social comparison and online social support individually separately mediate the positive relationship between the intensity of social media use and employment anxiety; and (3) self-esteem negatively moderates the effect of upward social comparison and effect of online social support on employment anxiety. The study underscores the importance of reasonable social media usage strategies, positive social perception, and healthy self-perception for fostering a positive employment mindset among youth.

Improving Well-Being Through Digital Detoxification Among Social Media Users: A Systematic Review and Meta-Analysis.

Digital detoxification is a conscious disconnection from all smartphone activities for a certain period of time, which has been undertaken as effective by researchers to improve well-being, but studies found inconsistent results, with a primary focus on negative well-being, thus necessitating a need to focus on the positive aspect. As a result, the current study conducted a systematic review and meta-analysis to assess digital detoxification and its influence on users subjective and psychological well-being (PWB). A comprehensive search (up to November 19, 2023) across databases such as PubMed, Scopus, Web of Science, Pro-Quest, and Google Search yielded a total of 26 eligible studies (18 for meta-analysis) comprising 8,147 participants (Mage = 25.20 years). The Studies' quality was assessed using Cochrane's updated Risk of Bias Tool, and statistical analysis was performed in R Studio. Digital detoxification was found to be effective in improving subjective well-being (SWB) (Standardized mean difference [SMD] = 0.21, 95% CI: 0.06, 0.34; p < 0.01, I2 = 73.6%, n = 14 papers), as well as PWB (SMD = 0.27, 95% CI: 0.09, 0.46; p < 0.05; I2 = 0.0%, n = 4 papers). Notably, we detected no publication bias but addressed funnel plot asymmetry using Trim & Fill. Moderation analysis revealed the impact of internet coverage, developmental status, location, intervention effectiveness, and risk of bias on the estimated effect size for SWB. Meta-regression highlighted the significant influence of mean age, and although no potential outliers were identified, influential plots are provided for transparency. Our findings consolidate the efficacy of digital detoxification, emphasizing the need for nuanced consideration of study factors. This study contributes to the ongoing discourse on digital well-being, offering valuable insights for researchers, practitioners, and policymakers.

Problematic Social Media Use Among Italian Midadolescents: Protocol and Rationale of the SMART Project.

BACKGROUND: Social media (SM) use constitutes a large portion of midadolescents' daily lives as a way of peer interaction. A significant percentage of adolescents experience intense or problematic social media use (PSMU), an etiologically complex behavior potentially associated with psychological distress. To date, studies longitudinally testing for risk or protective factors of PSMU, and collecting qualitative data are still scarce among midadolescents. Self-help interventions specifically targeting PSMU in this population and involving midadolescents in co-creation are needed. OBJECTIVE: The 2-year SMART multicenter project aims to (1) advance knowledge on PSMU; (2) co-design an unguided self-help app for promoting awareness and functional SM use; and (3) test feasibility and provide preliminary findings on its effectiveness to further improve and adapt the app. METHODS: The SMART project is organized in 3 phases: phase 1 will focus on knowledge advancement on PSMU and its risk and protective factors using a longitudinal design; phase 2 will explore adolescents perspectives using qualitative approach and will co-design an unguided self-help app for reducing PSMU, which will be evaluated and adapted in phase 3. Around 1500 midadolescents (aged 14-18 years) will be recruited in northern, central, and southern Italy to investigate the potential intra- and interpersonal psychological risk and protective factors for PSMU and define specific PSMU profiles and test for its association with psychological distress. Subjective (self-report) PSMU's psychosocial risk or protective factors will be assessed at 3 different time points and Ecological Momentary Assessment (EMA) will be used. Moreover, focus groups will be performed in a subsample of midadolescents to collect the adolescents' unique point of view on PSMU and experiences with SM. Those previous results will inform the self-help app, which will be co-designed through working groups with adolescents. Subsequently, the SMART app will be deployed and adapted, after testing its feasibility and potential effectiveness in a pilot study. RESULTS: The project is funded by the Italian Ministry of University and Research as part of a national grant (PRIN, "Progetti di Rilevante Interesse Nazionale"). The research team received an official notice of research funding approval in July 2023 (Project Code 2022LC4FT7). The project was preregistered on Open Science Framework, while the ethics approval was obtained in November 2023. We started the enrollments in December 2023, with the final follow-up data to be collected within May 2025. CONCLUSIONS: The innovative aspects of the SMART project will deepen the conceptualization of PSMU and of its biopsychosocial antecedents among midadolescents, with relevant scientific, technological, and socioeconomic impacts. The advancement of knowledge and the developed self-help app for PSMU will timely respond to midadolescents' increased loneliness and psychological burden due to COVID-19 pandemic and humanitarian crisis.

Mental health symptom burden in elite ice hockey players and its association with self-reported concussive events.

BACKGROUND: Some studies suggest that elite athletes experience adverse mental health symptoms at rates commensurate with the general population, despite the well-established buffering effects of exercise. Within contact sports, such as ice-hockey, recurrent concussions may be a source of this discrepancy. We compared the point prevalence of various mental health outcomes with other athlete and general population samples, as well as investigated their relationship with concussive events. METHODS: We surveyed 648 active ice hockey players from the top two men's tiers and the top women's tier in Swedish elite ice hockey on lifetime concussive events, hazardous alcohol use, problematic social media use, depression, anxiety, and burnout. RESULTS: Hazardous alcohol use was more prevalent among male ice hockey players (29.5% AUDIT-C ≥ 6) compared to other athlete and general population samples, while other mental health symptoms were less common. Female ice hockey players reported higher hazardous alcohol consumption (36.4% AUDIT-C ≥ 4) than another athlete sample and more burnout (19.1%) than the general population. After adjusting for covariates, athletes with 3+ concussive events had 2.1 times the odds of elevated depressive symptoms and 3.5 times the odds of elevated burnout symptoms compared to those with no concussion history. Treating lifetime concussive events as a continuous predictor revealed positive correlations with all outcomes except for hazardous alcohol use. CONCLUSIONS: Mental health outcome rates among active elite ice hockey athletes differ from those of other athlete and general population samples, whilst concussive events may be particularly linked to elevated symptoms of depression and burnout.

Influence of TikTok on Body Satisfaction Among Generation Z in Indonesia: Mixed Methods Approach.

BACKGROUND: As social media platforms gain popularity, their usage is increasingly associated with cyberbullying and body shaming, causing devastating effects. OBJECTIVE: This study aims to investigate the impact of social media on Generation Z users' body image satisfaction. More specifically, it examines the impact of TikTok on body image satisfaction among TikTok users aged between 17 years and 26 years in Indonesia. METHODS: The methodology used mixed-method approaches. Quantitative data were obtained from 507 responses to a questionnaire and analyzed using covariance-based structural equation modeling. Qualitative data were obtained from the interviews of 32 respondents and analyzed through content analysis. RESULTS: This study reveals that upward appearance comparison is influenced by video-based activity and appearance motivation. Conversely, thin-ideal internalization is influenced by appearance motivation and social media literacy. Upward appearance comparisons and thin-ideal internalization comparisons detrimentally impact users' body image satisfaction. CONCLUSIONS: The results of this study are expected to provide valuable insights for social media providers, regulators, and educators in their endeavors to establish a positive and healthy social media environment for users.

Clarifying the relationship between insecure attachment and problematic social media use across platforms: a network analysis.

BACKGROUND: Despite evidence suggesting that insecure attachment is a significant risk factor for Problematic Social Media Use (PSMU), there remains a lack of comprehensive studies exploring this relationship, and a unified understanding of its role has yet to be established. METHODS: We employed network analysis to construct an integrated model for examining the complex interrelations between negative emotions, trait and state attachment, motives, and PSMU across three platforms (i.e., WeChat, Sina Weibo, and TikTok), as well as for identifying potential mediating variables between attachment and PSMU. Data were collected from 685 young adults via online self-reported questionnaires. RESULTS: We found that negative emotions are positively correlated with insecure trait and state attachment but have a negligible direct relationship with PSMU. The conformity motive and state attachment security emerged as important central nodes when measured by strength, closeness, and betweenness. Moreover, attachment states and motives were found to be clustered. Such strong interrelationships were also evident between insecure attachment and PSMU, while trait attachment anxiety and avoidance were observed to be related to PSMU across various platforms. CONCLUSIONS: Our findings promote a deeper understanding of the relationship between insecure attachment and PSMU from a cross-platform perspective and offer novel insights into the mechanisms underlying their co-occurrence, which may guide the development of effective interventions for healthier social media engagement.

Adult attachment, social anxiety, and problematic social media use: A meta-analysis and meta-analytic structural equation model.

The relationship between adult attachment (anxious attachment and avoidant attachment) and problematic social media use is controversial and contradictory. Hence, the present study clarified the relationship between adult attachment dimensions and problematic social media use through meta-analysis. To better explain the relationship, this study also established meta-analytic structural equation modeling to examine the mediating role of social anxiety in the relationship. This study used CMA and R software for data analysis. Forty-five effect sizes were included in the study, including 11,746 individuals. Results showed that anxious attachment was strongly correlated with problematic social media use (r = 0.319, 95 %CI[0.271, 0.366]), whereas avoidant attachment was weakly correlated with problematic social media use (r = 0.091, 95 %CI[0.011,0.170]). Moderating effects showed that the relationship between anxious attachment and problematic social media use was moderated by the measurement instrument. Meta-analytic structural equation modeling showed that anxious attachment had a significant positive effect on PSMU through social anxiety, anxious attachment had a significant positive effect on PSMU through social anxiety. This study clarifies inconsistencies in the existing literature through meta-analysis, providing reliable conclusions and novel perspectives. It assists clinical practitioners in developing tailored treatment programs for practical interventions. It is suggested that treatment for problematic social media use requires attention to individuals with insecure adult attachment and social anxiety. For individuals with high anxious attachment and social anxiety, it is essential to help them manage their social media use effectively and reduce their dependence on it. Concurrently, interventions for attachment avoidant individuals should focus on enhancing their social self-confidence to reduce the influence of social anxiety on their social media use.

Mechanisms Linking Social Media Use and Sleep in Emerging Adults in the United States.

Social media use is associated with poor sleep outcomes. We aimed to extend previous research by examining how measures of social media use would affect two sleep characteristics: sleep quality and insomnia symptoms. In addition, we tested a serial mediation model linking social media use to sleep through increases in negative social comparison and pre-sleep cognitive arousal. Participants were 830 emerging adults (ages 18-30) who were recruited for an online survey study in February 2024. The sample was 63.1% female, with an average age of 24. We examined three measures of social media use: duration (minutes of daily use), frequency (number of weekly visits to social media platforms), and emotional investment (attachment to and integration of social media into daily life). Consistent with our hypothesis, greater emotional investment in social media and more frequent social media use were associated with poorer sleep quality and greater insomnia severity. We also found evidence supporting our hypothesized serial mediation model: emotional investment in social media and more frequent social media use were associated with increased negative social comparison, which subsequently increased pre-sleep cognitive arousal, which then led to poorer sleep outcomes. Our findings suggest that negative social comparison and pre-sleep cognitive arousal are important mechanisms linking social media use to poor sleep outcomes. Future studies should aim to test this serial mediation model using longitudinal data and experimental methods.

Impacts of digital social media detox for mental health: A systematic review and meta-analysis.

The impact of social media has been significant on various aspects of life, particularly mental health. Growing concerns about the adverse effects of social media use have prompted the exploration of experimental interventions, defined as digital detox interventions. However, it remains unclear whether digital detox interventions are effective for mental health outcomes. The aim of this study was to provide comprehensive insights into the effects of digital detox interventions on various mental health outcomes, including depression, life satisfaction, stress, and mental well-being. Following the PRISMA guidelines, systematic searches were carried out in online databases, including PubMed and ScienceDirect, within the publication range of 2013 and 2023. A total of 2578 titles and abstracts were screened, and 10 studies were included in the analysis. A risk of bias assessment was conducted using RoB 2.0 and the Newcastle-Ottawa scale, while statistical analysis was conducted using RevMan 5.4.1. Our data indicated a significant effect of digital detox in mitigating depression with the standardized mean difference (SMD: -0.29; 95%CI: -0.51, -0.07, p=0.01). No statistically significant effects were discerned in terms of life satisfaction (SMD: 0.20; 95%CI: -0.12, 0.52, p=0.23), stress (SMD: -0.31; 95%CI: -0.83, 0.21, p=0.24), and overall mental well-being (SMD: 0.04; 95%CI: -0.54, 0.62, p=0.90). These data underscore the nuanced and selective influence of digital detox on distinct facets of mental health. In conclusion, digital detox interventions significantly reduce depressive symptoms, suggesting that intentional reduction or cessation of digital engagement may help alleviate contributing factors. However, no statistically significant effects were observed in mental well-being, life satisfaction, and stress. This discrepancy may be due to the complex nature of these constructs, involving various factors beyond the scope of digital detox interventions.

Using Short-Form Videos to Get Clinical Trial Newcomers to Sign Up: Message-Testing Experiment.

BACKGROUND: Recruiting participants for clinical trials poses challenges. Major barriers to participation include psychological factors (eg, fear and mistrust) and logistical constraints (eg, transportation, cost, and scheduling). The strategic design of clinical trial messaging can help overcome these barriers. While strategic communication can be done through various channels (eg, recruitment advertisements), health care providers on the internet have been found to be key sources for communicating clinical trial information to US adults in the social media era. OBJECTIVE: This study aims to examine how communication source (ie, medical doctors and peers) and message framing of TikTok videos (ie, psychological and logistical framing) influence clinical trial-related attitudes, perceptions, and sign-up behaviors under the guidance of the integrated behavioral model. METHODS: This study used a 2 (source: doctor vs peer) × 2 (framing: psychological vs logistical) between-participant factorial design web-based experiment targeting adults in the United States who had never participated in clinical trials (ie, newcomers). A Qualtrics panel was used to recruit and compensate the study respondents (n=561). Participants viewed short-form videos with doctors or peers, using psychological or logistical framing. The main outcome measures included perceived source credibility, self-efficacy, attitude toward clinical trial participation, behavioral intention, and sign-up behavior. Structural equation modeling was used to analyze the direct and indirect effects of message factors on the outcome variables. Source (doctor=1; peer=0) and framing (psychological=1; logistical=0) were dummy-coded. RESULTS: Doctor-featured messages led to greater perceived source credibility (ß=.31, P<.001), leading to greater self-efficacy (95% CI 0.13-0.30), which in turn enhanced behavioral intention (95% CI 0.12-0.29) and clinical trial sign-up behavior (95% CI 0.02-0.04). Logistical barrier-framed messages led to greater self-efficacy (ß=-.09, P=.02), resulting in higher intention to participate in clinical trials (95% CI -0.38 to -0.03) and improved sign-up behavior (95% CI -0.06 to -0.004). Logistical barrier-framed messages were also directly associated with an increased likelihood of signing up for a clinical trial (ß=-.08, P=.03). The model accounted for 21% of the variance in clinical trial sign-up behavior. Attitude did not significantly affect behavioral intention in this study (ß=.08, P=.14), and psychological and logistical barrier-framed messages did not significantly differ in attitudes toward clinical trial participation (ß=-.04, P=.09). CONCLUSIONS: These findings advance our understanding of how people process popular message characteristics in short-form videos and lend practical guidance for communicators. We encourage medical professionals to consider short-form video sites (eg, TikTok and Instagram Reels) as effective tools for discussing clinical trials and participation opportunities. Specifically, featuring doctors discussing efforts to reduce logistical barriers is recommended. Our measuring of actual behavior as an outcome is a rare and noteworthy contribution to this research.

Social Media Use and Well-Being: A Systematic Review and Meta-Analysis.

Prior research has investigated the link between social media use (SMU) and negative well-being. However, the connection with positive well-being has not been extensively studied, leading to a situation where there are inconsistent and inconclusive findings. This study fills this gap by examining the correlation between excessive and problematic SMU and subjective as well as psychological well-being (PWB). We conducted a systematic search across databases such as PubMed, Scopus, and Web of Science, and gray literature sources such as Research Gate and ProQuest, yielding 51 relevant studies for meta-analysis, encompassing a sample size of 680,506 individuals. Employing the Newcastle-Ottawa Scale, we assessed study quality, whereas statistical analysis was executed using R Studio. Excessive SMU showed no significant association with subjective (ES = 0.003, 95% confidence interval [95% CI]: -0.08, 0.09; p = 0.94, I2 = 95.8%, k =16) and PWB (ES = 0.16, 95% CI: -0.15, 0.45; p = 0.26, I2 = 98%, k = 7). Conversely, problematic SMU showed a negative correlation with subjective (ES = -0.14, 95% CI: -0.20, -0.09; p = 0.00, I2 = 93.3%, k = 25) and PWB (ES = -0.19, 95% CI: -0.31, -0.06; p = 0.01, I2 = 95%, k = 5), with two outliers removed. No publication bias was detected. Subgroup analysis highlighted effects of "sampling method" (p < 0.05), "study quality" (p < 0.05), "developmental status" (p < 0.05), "forms of social media" (p < 0.05), and "type of population" (p < 0.01) on the estimated pooled effect sizes. Although univariate meta-regression showed the effects of "% of Internet users" (p < 0.05) and "male%" (p < 0.05), and multivariate meta-regression showed the combined effect of moderators only on the relationship between problematic SMU and subjective well-being.
